Is it permissible to use the reset + test buttons of an RCD plug adapter as on/off buttons for a 10A load?

I have a 2000W power saw which I want to switch on and off at the socket under load, ie. the tool's own switch will be permanently on. (The details are un-important.)

I have an extension cable with unswitched sockets, and want to use an RCD for safety. I don't really want to add a third component in the form of a switched multi socket adapter, and in any case like the idea of quick, colour-coded push-buttons to operate the saw.

Are the reset & test buttons suitable for such load switching?
 
No as they are designed as test switches and not for functional switching. They would fail eventually, probably quite quickly with a 10 amp load.
 
As above, a 2kW power saw will have a high inrush current so it will quickly burn the RCD contacts out.

Ideally you are looking for a "Direct On Line" starter such as this:

Most 3-phase starters can be wired for single phase, they are basically a 3-pole contactor and start/stop buttons to allow the windings of the contactor the be energised and de-energised. Also they release automatically on power fail, so it the mains returns after a fault the motor does not burst in to life!
 
Also if you are bying a "3 phase" starter it has to be rated at 6kW or more for your 2kW motor as they give the rating when running on 3-phase.
 
change the extension lead for one with switched outlets. if a switch on that fails, it's a cheap replacement.
 
Thanks for the advice, I'll probably go with a regular switched outlet as the direct online starter is probably overkill for the occasional use this will be put to.

Thanks
 
The good thing about an NVR is they switch off automatically if you get a power failure, in as a trip of the MCB or RCD, so when you switch the power back on the unit does not start up by itself, you have to reset the switch, I have them on all my large workshop tools, even the extractor.
